Re: [Amforth-devel] 2variable definition - 2 versions

Thanks for the reply. As usual, this leads to more questions.

Have the word definitions available at
http://amforth.sourceforge.net/words/ been updated to reflect this
change, or are they using the old definitions?

That makes sense to me, but I'm still interested in definition amforth uses:

http://amforth.sourceforge.net/words/XT_VARIABLE.html

Why "(CREATE) COMPILE COMPILE" instead of CREATE? What is (literal)
doing in front of the 2? Shouldn't sticking (literal) in the
definition be handled by ':' ? I take it that (unnamed) replaces ','
since we want to store the address in flash.

Thanks
